DESCRIPTION OF RELATED ART

With the emergence of smart phones in recent years, the demand forminiature camera lens is increasing day by day, but the photosensitivedevices of general camera lens are no other than Charge Coupled Device(CCD) or

Complementary metal-Oxide Semiconductor Sensor (CMOS sensor), and as theprogress of the semiconductor manufacturing technology makes the pixelsize of the photosensitive devices shrink, coupled with the currentdevelopment trend of electronic products being that their functionsshould be better and their shape should be thin and small, miniaturecamera lens with good imaging quality therefor has become a mainstreamin the market. In order to obtain better imaging quality, the lens thatis traditionally equipped in mobile phone cameras adopts a three-pieceor four-piece lens structure. And, with the development of technologyand the increase of the diverse demands of users, and under thiscircumstances that the pixel area of photosensitive devices is shrinkingsteadily and the requirement of the system for the imaging quality isimproving constantly, the five-piece, six-piece and seven-piece lensstructure gradually appear in lens design. There is an urgent need forultra-thin wide-angle camera lenses which have good opticalcharacteristics and the chromatic aberration of which is fullycorrected.
